Step-by-step explanation:
change the unit
50 km per 1 hour
50 km/h = 50,000 m/ 3600 s = 13.8 m/s
the lorry speed is 13.5 m/s or 0.3 m slower than the limit
Answer:
0.000174
3.5841 x 10^7
4.67 x 10^6
Step-by-step explanation:
1.74 x 10^-4 as an ordinary number
As an ordinary number, the decimal point will be moved 4 times to the left due to the negative power
Hence 1.74 x 10^-4 as an ordinary number
= 0.000174
358.41 x 10^5 in a standard form
In standard form, only one number will be before the decimal point, the number of times the decimal point is moved (to ensure that only the first digit is before the point) is added to the power of ten. Hence
358.41 x 10^5 in a standard form
= 3.5841 x 10^5+2
= 3.5841 x 10^7
4 670 000 in a standard form
As done above, only one digit will be before the decimal
4 670 000 in a standard form
= 4.67 x 10^6

Answer:
60
Step-by-step explanation:
Answer:
the area would be 36(pi) since you can't find out the exact value of pi (22/7) and where it would terminate so thats the most exact answer you can get. The circumference would be
Step-by-step explanation:
12/2 = 6
Area = (pi)radius^2
6^2 = 36
36(pi)
Circumference: (pi)d
12(pi)
For approximate area you multiply r^2 by 3.14
For approximate circumference you multiply diameter by 3.14
